On the influence of the tangential solar-motion component [PDF]

open access: yesSerbian Astronomical Journal, 2002
The influence of the tangential component of the solar motion (towards l = 90o, b = 0o) corrected for the value of the asymmetric drift, on the galactocentric orbits of selected nearby stars is studied.

Anomalies in the gamma-ray diffuse emission of the Galaxy and implications for the interpretation of IceCube results

open access: yesEPJ Web of Conferences, 2017
Several independent analyzes of Fermi-LAT results found evidences of an excess of γ -ray diffuse emission along the inner Galactic plane and of a related spatial dependence of the cosmic ray (CR) proton spectral index.

Search for Extended Sources of Neutrino Emission in the Galactic Plane with IceCube

open access: yesThe Astrophysical Journal, 2023
The Galactic plane, harboring a diffuse neutrino flux, is a particularly interesting target in which to study potential cosmic-ray acceleration sites. Recent gamma-ray observations by HAWC and LHAASO have presented evidence for multiple Galactic sources ...

Faraday Rotation as a diagnostic of Galactic foreground contamination of CMB maps [PDF]

open access: yes, 2012
The contribution from the residuals of the foreground can have a significant impact on the temperature maps of the Cosmic Microwave Background (CMB). Mostly, the focus has been on the galactic plane, when foreground cleaning has taken place.

The HESS Galactic Plane Survey [PDF]

open access: yesProceedings of the International Astronomical Union, 2009
AbstractThe H.E.S.S. Galactic Plane Survey (GPS) has revealed a large number of Galactic Sources, including Pulsar Wind Nebulae (PWN), Supernova Remnants (SNRs), giant molecular clouds, star formation regions and compact binary systems, as well as a number of unidentified objects, or dark sources, for which no obvious counterparts at other wavelengths ...

The HESS Galactic plane survey [PDF]

open access: yesAIP Conference Proceedings, 2017
The H. E. S. S. (High Energy Stereoscopic System) Galactic plane survey (HGPS) was performed with the H. E. S. S. I Cherenkov telescope array in Namibia from 2004 to 2013. In total +/- 2700 hours of high-quality observations of the Galactic plane are available in the Galactic longitude range of 250. to 65.

The gamma-ray and neutrino sky: A consistent picture of Fermi-LAT, Milagro, and IceCube results [PDF]

open access: yes, 2015
We compute the gamma-ray and neutrino diffuse emission of the Galaxy on the basis of a recently proposed phenomenological model characterized by radially dependent cosmic-ray (CR) transport properties.

Neutrino fluxes from the Galactic plane and the ANTARES limit

open access: yesEPJ Web of Conferences, 2016
The existence of cosmic neutrinos has been reported by the IceCube Collaboration. Though this measurement is consistent with an isotropic neutrino flux, a sub-dominant galactic component coming from extended regions such as the Galactic Plane cannot be ...

Chemical gradients in the Milky Way from the RAVE data. II. Giant stars [PDF]

open access: yes, 2014
We provide new constraints on the chemo-dynamical models of the Milky Way by measuring the radial and vertical chemical gradients for the elements Mg, Al, Si, Ti, and Fe in the Galactic disc and the gradient variations as a function of the distance from ...

New Constraints on the Galactic Halo Magnetic Field using Rotation Measures of Extragalactic Sources Towards the Outer Galaxy [PDF]

open access: yes, 2012
We present a study of the Milky Way disk and halo magnetic field, determined from observations of Faraday rotation measure (RM) towards 641 polarized extragalactic radio sources in the Galactic longitude range 100-117 degs, within 30 degs of the Galactic
